My modifications involve two power buttons, the new Picade HAT, and a single 12V power source. All links to where I bought the items are below as well.

The key features this setup offers is the ability to have a single power source with a master on/off button, and an additional button that utilises Picade HAT's Pi on/off feature. Both buttons light up when on for a nice visual feedback. Also, my setup allows you to have physical volume up/down buttons (missing from the HAT), and the wiring of both speakers together. A full circuit diagram is below too.

Unfortunately, I can't take credit for designing my build... I copied @Paulcheffus post and then asked him a 1000 questions. He's the real electrical genius and I want everyone to know.I can only take credit for the joystick/button/lighting upgrades as those were my ideas.

May I ask a question... are you happy with the design of two types of switches rather than using a 3rd party power solution (atxraspi, powerblock, etc) and having a single power button?

@Dyltone yes I know what you mean with the switches, but as I have the Picade HAT I had to use the two. This is because the HAT doesn't automatically turn on unless you press the power button, so I'd have needed a 2nd switch anyway.

Just thinking out loud, and not sure this would work. I'm would think you could have used the LED leads from a single power button to complete the start up circuit on the HAT power button or something similar.

Either way, beautiful work and thanks for sharing. I love this little cade.

Hi Below is a photo of my Picade mod [image] I used a 12v DC 5A power supply (just in case I want to later change the screen for a 12.1" in the future). This is fed to the ATXRasPi through a car 12v to 5v converter capable of supplying 3A. The ATXRasPi is used to control the power to the Pi from a push switch on the side of the cabinet. The homemade PCB on the right hand end of the Pi GPIO enables a script called from the menu to activate the ATXRasPi in the same way as pressing the switch. …

Thanks for that I did wonder why there was a white bit there, now I know!

I think I have 2 choices basically do what you have done.

or I noticed that the socket you use had the thread at the front, not behind, so I thought I could just make a slightly small hole in the panel and screw the thread into the hole, I shouldn't then need the nut on the other side to hold it in I am hoping at least.

This is my setup so far. Single power source with ATXRaspi. I still need to secure the Pi and do some cable management but overall I am very happy with the results. Thanks to Dyltone and Paulcheffus for answering all my silly questions and findon for the artwork.

Really impressed with this setup Luis. Actually have a few questions on this: Would you be able to sketch out the connections? So I am sure that this is what I am seeing: 1) your 12v Power source is fed into the cab, branched out to direct 12v power to lcd driver board and 12v in to the 12vto5V CPT.2) from 5V out from CVP goes to ATXRaspi and from there you power RaspPi via GPIO and not via micro usb. Am I correct?

Post-Edit: After seeing ATXRaspi intro video I realized that you must still power PI from micro USB, GPIO are used to send commands do Pi to enable boot/reboot/shutdown. #newbie

1) Correct2) The CPT that I got has a micro usb output that gets connected to the ATXRaspi 5v input and from there it gets connected to the Pie via USB A to Micro USB cable (i got this cable from the ATXRaspi website).

I've actually bought an OnOffShim as the ATXRaspi isn't readily available here in the UK, and all I need it for is turning on and safely shutting down. Maybe I'll just get a momentary instead. In fact I've found the exact same switch but a momentary one, so that's good.
